  1. OCR support | GroupDocs

    OCR support means the ability to connect an external module (library) for the recognition of printed text (optical character recognition, OCR) on images, either separate or embedded in documents. To connect OCR, you need to implement the IOcrConnector interface in the client code. The following example demonstrates how to implement the OCR connector using com.aspose.ocr library for text recognition in images. String indexFolder = "c:\\MyIndex"; String documentFolder = "c:\\MyDocuments"; // Creating an index Index index = new Index(indexFolder); // Setting the OCR indexing options IndexingOptions options = new IndexingOptions(); options....Conversion Product Solution GroupDocs...welcome to search over your PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX...

  8. Indexing with stop words | GroupDocs

    Stop words are frequently used words that do not carry a semantic meaning and can be removed from an index to reduce its size. You can enable or disable the use of stop words by calling the setUseStopWords method of the IndexSettings class. The default value is true, meaning that stop words are filtered during indexing and not added to the index. A list of stop words to use during indexing can be specified in the stop word dictionary....Conversion Product Solution GroupDocs...welcome to search over your PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX...

  9. Indexing additional fields | GroupDocs

    Sometimes when indexing, it is necessary to associate each document with certain additional metadata, for example, a set of tags, a number in the library catalog, the subject of a document, etc. To accomplish this task, additional fields can be added to each indexed document in addition to those already in the document itself. Additional fields are associated with the document through the arguments of the FileIndexing event that occurs before indexing each added document....Conversion Product Solution GroupDocs...const documents = [ 'Lorem ipsum.pdf' , 'English.docx' , 'Lorem ipsum...

  10. Merge indexes | GroupDocs

    The merge operation is designed to combine two or more indexes into one index to accelerate the search and to simplify the work with indexes. When merging, only the index at which the merge method was called is changed. This index as a result of the operation contains all the documents that were contained in all indexes together. The second index or index repository after the merge can be deleted to free up disk space....Conversion Product Solution GroupDocs...welcome to search over your PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX...
